. and a border wire for the fabric and which acts as a stabilizer for the border wire, assuring such wire returning to its normal or original position when the spring or more particularly the fabric is free of strain.

The invention consists in the details of construction and in the combination andarrangement of the several parts of my 1mproved attachment for a bed spring whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient'and advantageous for use, as will be hereinafter more fully setforth.

The novel featuresof my invention will hereinafter be definitely claimed;

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein Figure 1 is a view partly in section and partly in elevation illustrating an attachment constructed in accordance with an em bodiment of my invention, a second position of certain of the parts being indicated by broken lines;

Figure 2 is a view in top plan of the attachment as illustrated in Figure 1, the adjacent portions of the spring proper belng fragmentarily indicated by broken lines;

Figure 3 is a view in top plan of the body or attaching member of the attachment unapplied; t

Figure 4 is a sectioinal view taken substantially on the line 44 of Figure 1.

As disclosed in the accompanying drawing, my improved attachment comprises a.

body member B substantially U-shaped in cross section and having its side members or walls 1 in spaced relation and gradually decreasing in height from one end of the member B to the other. The upper marginal portions of the walls 1 are defined by the outstanding flanges 2 serving to strengthen said body member B, said flanges 2 having extensions 3 disposed beyond the high end of the walls 1 and adapted to rest from above upon a side member 4 of the bed spring. These extensions 3 are provided with the openings 5 whereby the'body member B maybe riveted or otherwise positively secured to the member 4'. g I r The base portion of the body member-B at its high end is extended, as at (Leach of the extended side wall portions 1" being provided in its upper marginal portion immediately adjacent to the side wall 1 proper with an uwardly facing open recess 7 which is adapted to receive the lower marginal portion of the depending flange of the member 4 when the body member B is in applied position whereby said body member B is effcc tively maintained in applied or working position.

' Extending between the side walls 1 adjacent to the high-end of the body'memb-er B is a rigid arm 8 held in applied position i by a rivet 9o'r' the like disposed through the sidewalls 1 and the arm 8. The lower or inner end of the arm 8 has direct contact with the lntermediateor base portion of the body member B whlereby said arm, 8 is effectively held against rocking movement about its connection 9. I

The opposite end portion ofthe arm 8 extends outwardly beyond the side walls 1 of the body member B, as is particularly illustrated in Figure 1, and attached, as at 10, to said outer end portion of the arm 8 is an extremity of a retractile coil spring 11. 8

The opposite end portion of this spring is attached, as at 12, to the upper portion of a rigid link 14. This link 14 extends between the side portions of the walls 1 of the body member B at their outer or low portions and is pivotally engaged with the rivet 15 or the like interposed between and carried by the side walls 1.

The outer end portion of the link 14 is 'pivotally connected, as at 16, between the side walls 17 ofan elongated member M. This member M is incross section substantially in theform of an inverted U and the outer extremity of the intermediate portion 18 thereof is provided with an extended tongue 19 which is adapted to be disposed around the border wire 20 of a bed fabric of a type commonly in use. The outerend of the link 14 at its outer marginal portion is provided with an outstanding lug 21 with 1 which the adjacentend of the intermediate portion 18 of the member M constantly abuts when the device is in applied or working position.

As pressure or strain is imposed upon the bed fabric and as the border wire 20 has a tendency to move downwardly, the member M will have aninward oscillating movement to a position substantially indifated by broken lines in Figure 1 and'with the link 14: having swinging movementinwardly of the bed fabric against the tension of the spring 11. When such pressure or strain is released, the spring S, which is constantly urging the link 1a in an opposite direction, will assure the border wire 20 returning to its normal or originalposition. By thismeans, the life ofthe spring is materially prolongcdand at the same time, assuring the maintenanre oi its original style or shape.

In practice, any number of my iin n-ovetl attachments may be employed but I find that good results can be obtained by. apply ing one of the attachments to each of. the side rails 4 of the frame proper at substantially the longitudinal center thereof, \Vhen so arranged, it will be understoodthatone of the devices eoacts with the othelwin a manner to effectively eliminate side movement or rockinq of the bed fabric and thus increase the eihciency of the bed spring.

Then the attachment is applied, it is also to be understood that the member H extends inwardly from the associated side rail 4. a

From the foregoing description it. is

thought to be obvious that an attachment for a bed spring constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reasonl do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out. my invention in practice except; as hereinafter claimed.

.1 claim In combination witha bed spring includinga frame and a top border wire, a member secured. to the frame and extending laterally therefrom, said member being in cross sectionsubstantially u shapetl, an arm fitting within said member and secured thereto, an end portion ot'lth e arm having directabutting contact against the bottom of the LLshaped memberto holdthearm against rocking movement, a link pivotally connected with said member, a retractile spring interposed between and secured to the a-rnrand link, and an elongated mem ber having one. end portionsecuredtothe border wire and its opposite end portion pivotally connected with the. link.

In testimony whereof. I; hereunto .aflix my signature.
